Abstract

Based on the conducted research, indicators for assessing the accident risks of trucks on mountainous curvilinear sections of highways were developed and scientifically validated. These indicators are based on the ratio between the actual vehicle speed and the critical speed of stability loss. The limit states of the truck stability loss were investigated based on the conditions of sideslip, rollover, and course stability. For the assessment and management of the accident risks of trucks under mountainous conditions, based on the obtained integral dynamic indicators, it is proposed to introduce a reserve value of stability risk, which makes it possible to quantitatively estimate the probability of accident occurrence.
